sync.nc {RNetCDF} | R Documentation |
Synchronize an open NetCDF dataset to disk.
sync.nc(ncfile)
ncfile |
Object of class " |
This function offers a way to synchronize the disk copy of a NetCDF dataset with in-memory buffers. There are two reasons one might want to synchronize after writes: To minimize data loss in case of abnormal termination, or to make data available to other processes for reading immediately after it is written.

## Create a new NetCDF dataset and define two dimensions nc <- create.nc("sync.nc") dim.def.nc(nc, "station", 5) dim.def.nc(nc, "time", unlim=TRUE) ## Create two variables, one as coordinate variable var.def.nc(nc, "time", "NC_INT", "time") var.def.nc(nc, "temperature", "NC_DOUBLE", c(0,1)) ## Define variable values mytime <- c(1:2) mytemperature <- c(0.0, 1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9) ## Put the data var.put.nc(nc, "time", mytime, 1, length(mytime)) var.put.nc(nc, "temperature", mytemperature, c(1,1), c(5,2)) ## Synchronize to disk sync.nc(nc) ## Now the data can be read var.get.nc(nc, 0) var.get.nc(nc, "temperature") close.nc(nc)
